独立主格结构的介词问题
____,the hunter went into the forest.
a.a gun on shoulder b.a gun was on his shoulder
c.gun on shoulder d.a gun being on shoulder
这题答案是C,为什么不xuanA呢?是介词on有什么特殊限制,导致了前后名词都不能加代词或者冠词吗?

Answer 1

是一种省略.说全就是with a gun on his shoulder.把with和冠词代词都省了.还有一种情形也不加冠词就是倒装的让步状语,例如 Boy as he is,he has already been in charge of taking care of his families.
